This is an antique Victorian or Edwardian tortoiseshell sailing ship brooch. It is not marked. The brooch is very deeply and intricately carved or molded. It has two masts and six sails. There are carved waves splashing on the bottom of the ship. The brooch is a C clasp. The brooch measures 1-3/4 inches in diameter. It is in very good condition with no breaks or cracks. It may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
